About 340 residents were under mandatory orders to leave the Fawnskin area and another 1,200 voluntarily left their homes in the resort community of Green Valley Lake, Forest Service spokeswoman Carol Beckley said Sunday.

However, cooler temperatures were expected to aid firefighters Sunday and the fire was headed northwest away from the homes, Beckley said. The fire was at least at least 10 miles (16 kilometers) from the nearest desert community.

"Right now, it doesn't appear they're in much danger," she said. "The fire would have to travel quite a bit."

Gov. Arnold Schwarzenegger declared a state of emergency for San Bernardino County on Saturday, clearing the way for state government assistance with costs related to the fire.

The fire, which remained under investigation, burned several outbuildings at a campground. About 1,080 firefighters were aided by 12 fixed-wing aircraft, 27 hand crews and 15 bulldozers.
